COMBINED SOLE-EDGE TRIMMER AN D TRlMMlNG-TOOL GRINDER.-

SPECIFICATION forming part of Letters Patent No. 253,911, dated February21, 1882.

' Application filed November 12, 1881. (No model.)

To all whom it may concern p Be it known that I, SAMUEL N. OORTHELL,

of Quincy, State of Massachusetts, have in- Figure 1 is a side elevationof a machine em bodying myimprovement, and taken as viewed from theright in Fig. 2. Fig. 2 shows in front elevation (taken as from the lefthand in Fig.

portion of the machine.

1) the right-hand portion of the machine, being that portion principallyshown in Fig. 1. Fig. 3 is an elevation taken from the same standpointas Fig. 2, but showing the left-hand Fig. 4 is a top plan view of thegrinder as secured to the supporting-pillar of the machine, which pillaris shown in transverse section. Fig. 5 is a detached view of thegrinder, taken as viewed from the right in Fig. l and from the rear inFig. 2.

In said views, A represents a standard on which the operative parts aremounted, the same being supported by its base B. A short arbor, a, isjournaled in suitable bearings formed upon or secured to said standard,and upon said arbor is secured a small pulley, b, which receives thedriving-belt leading down from the counter-shaft. On said arbor, outsideof said standard, is secureda speed-pulley, c, on which is placed belte, which at the top engages pulley E0 on arbor k, which carries therotary rand cutter or tool m. A pulley, d, is also secured on arbor a,centrally in standard A, and through its belt f, which engages pulley won arbor 0, serves to rotate the edgetrimming cutter h and shank-cutteri, which are carried by said arbor 0, said arbors 7c and 0 beingjournaled in head j, the essential parts thus far described being thesame as in my former Letters Patent No. 236,145, dated J anuary 4, 1881;but the said driving parts may be varied from the foregoing, and therand= cutter m and edge-cutter h may both be mounted upon the samearbor; but I prefer the arrangement described and shown.

The toothed edge-cutter h.(clearly shown in Fig. 4 as arranged to besharpened) requires frequent sharpening, both by reason, of itsnecessary high workingvelocity and the gritty and abrading nature of theleather on which it acts and in order that said cuttermay be thussharpened with the least possible loss of time and at the minimum ofexpense, both in regard to the machine on which such sharpening isefiected and the facilities thereby afforded, I have invented my presentimprovement.

A shelf or bed-plate, l, is secured to stand ard A by its bracket-arm n,Figs. 1 and 2. Said plate Z is formed with guiding side ledges, as shownin Fig. 3, and between said ledges the supplemental bed 0" is arrangedto be lineally adjusted, and is secured'in position by its locking-screw3 Upon said bed 1' is formed the standard 8, in which is journaled thearbor p, on which is mounted the solid emery grinding-disk t and thepulley 2, which latter, by means of the lineal adj ustmentof plate 0,may be brought into contact with belts (or the belt that drives theedge-cutter) with such degree of force as shall insure the rotation ofarbor 1) by the contact of the belt with pulley e.

In plate I is formed an opening, o, Figs. 2, 4, in which is secured thevertical standard g, the shank whereof is of less diameter than thewidth of said passage, whereby said standard may be adjusted not only atthe requisite distance from disk t, but also in the desired positioneither to the right or left thereof, as the form of the teeth ofedge-cutter It may render necessary, a broad collar on said standard 9bridging across opening 1;, and an equally broad washer between bed landset-nut a serving to seat said standard in said opening. When standard 9is thus properly adjusted relatively to disk t, and cutter It requiressharpening, the same is removed from its arbor 0 and placed on standard9, as shown in Figs. 1,

2, and 4, and pulley 2, by the means described,

is brought into contact with its actuating-belt, when, by the propermanipulation of the cut ter on the standard 9, its teeth aresuccessively be brought into contact with, to, be separated brought incontact with the grinding-disk, and from, and to be actuated by, thecutter-driv- 15 may be not only ground to the desired sharp ing belt,when so brought into contact therecutting-edge, but the plane or face ofeach with, by means substantially as specified.

When not in actual use for grinding pulley with its pulley z, and diskt, and adjustable 20 z is retired from contact with its belt, and atrelatively to the driving-belt, substantially as such times the grinderis inactive and exempt specified.
